The difference between sensitivity analysis for integer linear programming problems and linear programming problems is:

1. with integer problems, any changes in the constraint coefficients only cause integer changes in the decision variables and the optimal solution.
2. with integer problems, small changes in the objective function coefficients can cause small changes in the constraint coefficients.
3. with integer problems, small changes in the constraint coefficients only cause very small changes in the decision variables and the optimal solution.
4. with integer problems, small changes in the constraint coefficients can cause much larger changes in the decision variables and the optimal solution.
